Which of these colours is NOT used in the resistor value colour code?

Resistor color coding uses a fixed set of colors to represent digits. The ten standard colors map to the digits 0 through 9: black, brown, red, orange, yellow, green, blue, violet, grey, and white. Turquoise isn’t one of these colors, so it has no assigned value in the code. Since there’s no digit, multiplier, or tolerance associated with turquoise, it can’t be used in the resistor value color bands. The other colors listed all have valid, defined values, while turquoise does not, which is why turquoise is not used.
